The Triumph America front and rear turn signal bulbs utilize a 5008 or 232 size specification for replacement applications. The replacement chart covers vehicle production spanning 2007 to 2016 with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 5008 and 232 are the two bulb types specified across all front and rear turn signal positions on the Triumph America from 2007-2016.
The 5008 is a single-filament, 12V bulb with a BA15s bayonet base, classified as a lower wattage variant of the 1156 under the ANSI standard used in the US and Canada.
The 232 is a 12V, 3W festoon bulb with an SV8.5 base, also conforming to the ANSI standard for the US and Canadian markets. Festoon bulbs are cylindrical in form and make contact at each end rather than through a base socket.
The BA15s bayonet base of the 5008 and the SV8.5 festoon base of the 232 are physically incompatible with each other, meaning the two bulb types are not interchangeable despite sharing the same 12V operating voltage.
On the Triumph America, the front turn signal position for 2012 and 2014 uses the 232 festoon bulb rather than the 5008 specified for all other years in that position.
The rear turn signal position uses the 232 for 2008, 2010, and 2011, while the 5008 is specified for all remaining years in that position.
Because the front and rear turn signal positions do not always share the same bulb type within a given model year, the position must be confirmed before selecting a replacement bulb.
